Disconnected from FC 27 servers in game and in menus about every 15 minutes

I have tried these solutions they don't work:

• Flush DNS & Reset IP Stack: In Windows, open Command Prompt as Administrator and run the following commands in order, then restart your PC:
  • ipconfig /flushdns
  • netsh int ip reset
  • netsh winsock reset
• Switch to Public DNS: Updating your network adapter IPv4 DNS to Google DNS (8.8.8.8 / 8.8.4.4) or Cloudflare DNS (1.1.1.1 / 1.0.0.1) helps prevent packet timeout during transition screens.
• Delete Corrupt Local Profile / Temp Files: Exit the game, go to Documents > FC 27 (or in-game under Customise > Profile > Delete), and remove any old personal settings or temp squad files that may fail to sync with the Ultimate Team cloud save.
• Add Windows Defender & Firewall Exclusions: Ensure FC27.exe, EADesktop.exe, and the EA AntiCheat services are added as exceptions in your firewall to prevent security sweeps from dropping background handshake connections during loading screens.
• Check EA Connection Quality Report: Run the official EA Connection Quality Report tool to monitor packet loss and jitter spikes that might not show up on a standard internet speed test.

I get disconnected when:

• End of a game when the result is loading and I am disconnected and sent back to menus
• Entering a game, black screen with loading icon on bottom - will not go away and I have to close the game - enter ultimate team and get DC warning message
• When trying to submit a squad in the gallery
• After trying to send players to the club after opening a pack
• Trying to change the tactics of my squad in the menu
• Trying to add players to the squad
• When trying to check season objectives and trying to claim season objective rewards

Nice!
